javascript - railscast 205

I added the following into a page of one of my post view in rails.
However when I click on it it doesn't bring up the "Hello UJS!" what am
I missing here?

    <script
src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"
type="text/javascript" charset="utf-8"></script>
    <script type="text/javascript" charset="utf-8">
      $(function() {
        $("#alert").click(function() {
          alert(this.getAttribute("data-message"));
          return false;
        })
      })

    </script>

     <h1><a href="#" id="alert" data-message="Hello UJS!">Click
Here</a></h1>

Try:

<h1><a href="#" id="alert" data-message="Hello UJS!">Click

Here
